My question is: What on earth is icing sugar? do you mean Confectioner's Sugar?...Please Help I really do wanna try making this...Thank you =) & thank you for sharing this recipe too =)

Rubycandy i think is powder sugar... I JUST TRIED IT TODAY AND IS DELICIOUS, SO CREAMY, thank u for the recipe... :)

Will this hold up for a cake filling? Sounds delish!

Yes, confectioners sugar is icing sugar. It's pretty soft for a filling, much like whipped cream.

I used banana pudding instead of flavored cream cheese. It was a little on the salty side. So I added three more table spoon of sugar and one more tea spoon of pudding. It tasted great and fluffy and just sweet enough. I guess I will be experimenting with other flavors of pudding:)

Pinar - did you use pre-made pudding?

I did use instant pudding. It really tasted good.
